Be described in detail below in conjunction with the detailed description of the invention of accompanying drawing to elevator oscillation damping method of the present invention.
As shown in Figure 1, a kind of elevator oscillation damping method, comprises step:
S110, obtain current elevator actual car load-carrying, current elevator floor position;
S120, choose and differ the car weight in preset range with the load-carrying of described elevator actual car from the car weight of record, and using the car weight chosen as current car load-carrying;
S130, corresponding relation according to the car weight of record, the swing offset amount of elevator floor position and servomotor, determine the swing offset amount of the servomotor corresponding with current car load-carrying and current elevator floor position;
S140, to regulate according to the swing offset amount determined and be arranged on the described servomotor of leading on boots.
Because the elevator actual car load-carrying obtained when elevator runs is not necessarily equal with the car weight of record, and the impact that difference load-carrying is within the specific limits vibrated car level is almost identical, so after obtaining current elevator actual car load-carrying, can choose from the car weight data of record and differ the car weight in preset range with this elevator actual car load-carrying.The data packet of the car weight such as recorded is containing 1000Kg (kilogram), 1190Kg, 1270Kg, 1340Kg ... preset range is 50Kg, the elevator actual car load-carrying obtained is 1030Kg, then choosing car weight is that the data of 1000Kg are as current car load-carrying.Preset range needs to arrange flexibly according to the closeness of the car weight of record, and when the car weight interval of recording is less, preset range is less, and when the car weight interval of recording is larger, preset range is larger.When the load-carrying of elevator actual car identical with two car weight differences of record and all in preset range time, any one of selection two car weight is as current car load-carrying, when two car weight differences of the load-carrying of elevator actual car and record are all in preset range, but a difference is larger, when a difference is less, select the car weight less with elevator actual car load-carrying difference as current car load-carrying.
After obtaining current car load-carrying and current elevator floor position, during in order to determine elevator real-world operation, servomotor needs the swing offset amount regulated, need the corresponding relation of swing offset amount of test record car weight in advance, elevator floor position and servomotor, the corresponding relation of the swing offset amount of wherein said car weight, elevator floor position and servomotor can be determined by following manner:
Each grade is divided into by from the unloaded car weight fully loaded to car of car,
Obtain the swing offset amount of elevator servomotor when each floor position under each grade car weight, and record the corresponding relation of swing offset amount of car weight, elevator floor position and servomotor.
Car zero load refers to that car does not carry the situation of any load, and car is fully loaded with the situation referring to car carrying peak load.Unloaded for the car test car weight fully loaded to car is divided into each grade, one or several load-carrying numerical value can be chosen test in each grade interval.Such as, be 1000Kg when car is unloaded, car at full load is 2000Kg, 1000Kg-2000Kg is divided into 10 heavy-duty class, i.e. 1000Kg-1100Kg, 1100Kg-1200Kg ..., then choose 1040Kg, 1070Kg, 1130Kg ... etc. testing, effectively reduce the work capacity that swing offset amount obtains, improve the efficiency that swing offset amount obtains.
After having divided the grade of car load, need from each grade car load, choose data to test under each elevator floor position, obtain the swing offset amount of the servomotor under each condition, wherein obtaining the step of elevator swing offset amount of servomotor when each floor position under each grade car weight can comprise:
Gather the acceleration signal of elevator horizontal vibration when each floor position under each grade car weight;
Each acceleration signal according to gathering determines the control signal slowing down car vibrations accordingly;
Regulate servomotor according to each control signal, obtain the swing offset amount of elevator servomotor when each floor position under each grade car weight.
Acceleration signal can be gathered by existing acceleration/accel collection plate, and each acceleration signal of collection can be transferred to existing controller and store.Controller, also for the determination of control signal and the driving of servomotor, namely specifically regulates the step of servomotor all can realize according to method existing in prior art according to acceleration signal determination control signal and according to control signal.The expected value of control signal is that car vibrations is kept to 0, after determining control signal, namely can drive the servomotor of leading on boots according to this control signal, thus the swing offset amount of elevator this servomotor when a certain floor position under obtaining corresponding car weight.
According to the corresponding relation of the car weight of record, the swing offset amount of elevator floor position and servomotor, namely the swing offset amount of the servomotor corresponding with current car load-carrying and current elevator floor position can be determined, then according to this swing offset amount, servomotor is regulated, servomotor rotarily drives transmission device slide unit and spring etc., it is stressed that boots are led in change, thus slow down car vibrations (expected value is 0).
